connncricur, ASSIGNOR TO THE SPECIFICATION forming part of Letters Patent No. 331,180, dated November 24, 1885.

Application filed June 8, 1885. Serial No. 167,999. (No model.) I

Be it known that I, RUssELL A. BELDEN, a citizen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and usefullmprovements in Turn-Tables for Hat- Forming Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as .will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to simplify and improve the construction of the turn-table itself, and of the mechanism by which it is supported and rotary movement is imparted thereto. Heretofore the construction of this part of the machine has been'such that a central support for the turn-table within the ex haust-tube has been necessary, and rotation could only be imparted to the turn-table by means of gearing. The central support and the gearing have both been found seriously objectionable, the construction as a whole be ing complicated, expensive, difficult to keep in repair, and noisy, in addition to which the quality of the hat-bodies formed upon the cone has been variable, owing to the'fact that the current of air through the exhaust-tube was broken and made irregular by the obstructions necessary to support the turn-table, and also by the fact that the construction permitted an escape of air otherwise than straight down through the exhaust tube. Still another objection to the construction heretofore in use has been that the dust collected' to such an extent upon the working parts as to-interfere with the running of the machine; and frequently to clog it, thus rendering it necessary to stop the machine to clearaway'the accumulation of dust. .Stoppage of the machine was also necessary when any'adjustment of the turn-table was found necessary,

I have succeeded in devising a novel construction and arrangement of turntable byv which I am enabled to do away with the central support, thus giving me an unobstructed and air-tight exhaust-tube, thereby removing the dust nuisance, and which also enables me to wholly dispense with gearing, and to run the turn-table by a belt, thus rendering the machine much less expensive to construct, and easy and light to run. I have, moreover,

simplified and perfected the details of con-' struction in various respects, as will be hereinafter fully explained, and then specifically pointed out'in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a central vertical section of the exhaust-tube and turntable, and also showing the manner in which the turntable is supported and rotation is im-' parted thereto. Fig. 2 is a plan view upon a reduced scale withrthe turn-table removed; Fig. 3, a side elevation corresponding therewith; and Fig. 4, a detail sectional viewon the line a: a; in Fig. 2, illustrating one of the oilcups in the ring.

Similar letters denote like parts in all the figures.

A is the bed-pl te; B, legs, and C ,the exhaust-tube. Y

D is arin'g to which the exhausttube is riv eted, and which is supported by bracketsE,

bolted to the under side of the bed-plate, and

to which the ring itself is securely bolted. Any number of brackets may of course be used, althoughin practice I have found three; The brackets are preferably quite sufficient. made U-shaped, as shown,'in order to accom-' modate a wide belt flange, aswill be more fully explained. 1 4 1 F indicates heavy-lugs cast integral with or secured to thering upon its under side. These lugs are preferably inclined inward slightly, as shown in Fig. 1, and are provided near their lower ends with slots or elongated openings G, to receive the journal-pins H, which carrythe supporting-rollers K.

As shown in Fig. 1, the journal-pins have vertical movement in slots. G. The rollers project through openings L,in' the ring and form the sole support for the'turn-table M.

The adjustment of the turn-table is effected by means of screws N, which pass through the ends of lugs F and bear upon the journal-pins. I have shown the turn-table as supported and carried by three rollers, which is the number I preferably use. 7 7

It will readily be seen that'should adjust ment of the turn-table become necessary from any cause whatever it may be almost instantly too accomplished by raising or lowering one or more of the screws N, which does not necessitate stoppage of the machine.

' The exact shape of the turntable is not of the essence of my invention, although I preferably construct it substantially as shown in Fig. 1. The bed-plate has a central opening, 0, through which the belt-flange]? of the turntable passes.

P is a lip, which I preferably cast at the lower edge of the belt-flange, the object being to prevent the belt from running off while in use. Ample space for the lip is allowed between the flange and the brackets, the latter serving as guards to prevent the belt from dropping down under any circumstances. The top of the turn-table is of sufficient diameter tomore than cover the opening through the bed-plate, so as to prevent any appreciable escapeof air under the turn-table.

- Q indicates the central depression in the turn-table in which the cone rests. The latter has not been shown for the reason that it forms no part of my present invention.

It indicates a downwardly-turned lip forming the wall of the central opening through the turn-table. This lip rests in a channel, S, at the inner edge of the ring, but without hearing thereon, the object being to prevent the escape of air and at the same time to cause no friction.

,As stated above, the turn-table is carried wholly by rollers K, which are so shaped and adjusted as to have bearing-surfaces parallel with the under side of the turn-table, as at T. The lateral or axial bearing of the turn-table is upon the edge of the ring, as at T. When properlyadj usted therefore, the turn-table only touches the edge of the ring and the surface of the rollers.

In order to make the axial bearing of the turn-table practically self-oiling, I have provided'oil-cup U in the top of the ring, which has side openings, U, leading through the edge of the ring, whereby the oil is conveyed to the bearing of the turn-table. These oil-cups may be filled without removing the turn-table, openings (notshown) through the turn-table being provided for that purpose.

1] indicates plugs, of leather or wood,which nearly close openings U, and just permit sufficient oil-to pass through to cause the turntableto run smoothly.

W represents the driving-belt, which runs upon flange I, whereby motion is imparted to the-turn-table.

. I do not desire to limit myself to the exact construction shown, as it is obvious that the details may be varied within reasonable limits without depart-ing from the spirit of my invention.

3 I claim---.

1. Ina hat-forming machine, the combination, with the ring and the rollers carried thereby, of the turn-table carried by said rollers and having a downwardly projecting flange which bears against the edge of the ring and carries a belt whereby motion is imparted to the turn-table.

2. The bed-plate, brackets secured thereto, a ring carried by said brackets, and rollers carried by said ring, in combination with the turn-table having a downwardly-projecting flange which bears against the ring and is adapted to carry abelt whereby motion is imparted to the turn-table.

3. The turn-table having a downwardlyprojecting flange adapted to carry a belt, in combination with a ring carrying rollers which support the turn-table, and having oilcups with openings through the outer edge of the ring whereby, the bearing of the turntable on the ring is kept constantly oiled.

4. The bed-plate, U.-shaped brackets se cured to said bed-plate, and a ring carried by said brackets, and having a series of rollers,

in combination with a turn-table carried by.

said rollers and having a downwardly-projecting belt-flange with a lip. P, and a belt upon said flange.

5. The bed-plate having a central opening, a ring carrying rollers and having a notch at its inner edge, and brackets connecting the ring to the bed-plate, in combination with a turn-table carried by said rollers and bearing againstthe outer edge of the ring, the upper surface of said turn-table being made to cover said central opening and being provided with a downwardly-turned lip engaging the notch in the ring, whereby the escape of air under the turn-table is prevented, but the turn-table has no bearing except upon the rollers and the outer edge of the ring. a

6. The ring having openings L and lugs F, the latter having slots G, in combination with the rollers whose journal-pins rest in said slots, the turn-table carriedby said rollers,

and screws N, which bear against the journalpins, whereby said journal-pins and the rollers carried thereby may be raised or lowered to adjust the turn-table.

7. The turn-table having a beltflange and the ring having rollers upon whichthe turntable. rides and a bearing at its outer edge for the belt-flange, in combination with an air-tight exhaust-tube. 8. The exhaust-tube and the ring carrying a series of adjustable rollers, in combination with the turn-table having a belt-flange and a lip which closely fits the inneredge of the ring to prevent escape of air, but which bears only upon the rollers-and upon the outer edge of the ring, whereby all supporting mechanism within the exhaust-tube is dispensed with. Intestimony whereof I affix my signature in presence of two witnesses.
